Question

integral(-1/(x ln x))dx = Integral(1/y) dy

Answer 1

integral(-1/(x ln x))dx = Integral(1/y) dy
= ln(ln(x)) = ln(y) +c
= ln(x) = y +c
Is this correct?

Answer 2

u missed a *minus* sign
integral(-1/(x ln x))dx = Integral(1/y) dy
=- ln(ln(x)) = ln(y) +c
=- ln(x) = y +c

Answer 3

oh... hehe apart from that sorry =)

Answer 4

yes, apart from that its absolutely correct.

Answer 5

because the site i am reading has "y = c ln x"

And that doesn't seem right...?

Answer 6

no, i don't think thats correct.

Answer 7

He even misses the minus sign also. Thanks for confirming this for me.

Answer 8

ok, welcome ^_^
